Alcohol has been used resposibly by the majority of society since it existed. I will probably have a beer this evening and feel a slight buzz, with no major change in my personality or feeling.
You cannot say the same for HARD drugs. Like I say, they are a different animal.
I thoroughly disagree with you. Your argument has is based on some assumptions and conventions that make an easy 1-to-1 equivalence pratically impossible. #1, alcohol is socially acceptable, so you'd expect many 'social' users of alcohol wouldn't cause many problems, since they're not hard-core.
Users of illegal drugs are, almost by definition, hard-core. They're willing to break the law to get them, so you'd EXPECT more chaos from those willing to use them.
Then you lump a whole bunch of drugs into the "HARD" drugs category... nebulous, anecdotal opinion on your part, not fact.
Many of these 'hard' drugs are a different animal, because most people would never use them.
In the end, this argument that alcohol is used responsibly, while others would not, is built on a false foundation -- that alcohol is used responsibly. Is an alcoholic who never gets busted for DUI, never gets arrested for being drunk in public, but nevertheless ruins his family with his addiction any better than a heroin addict who does the same thing?
The fallacy that alcohol 'isn't that bad' is simply perpetuated by those who enjoy it. Objectively, alcohol is a very dangerous drug, legal or illegal.
Coupled with its social acceptability, it's the drug you should worry about. Heroin will never be socially acceptable. Cocaine was, in the 70s, in certain circles, but is not any longer. Pot can be acceptable, but in most places not.
If you're really worried about the damage of drugs, focus on their social acceptability, not their legality. If alcohol were the social pariah that PCP is, noboby would drink it, legal or not.
As for Jesus, so what? He's probably the one guy on Earth who really could 'hold his liquor'. Bully for him. I'd bet that if the society were 'smoking the herb' in his day, he'd have tried that, too.
I've got some oxycodone left over from a back injury, and I could go crush one up and take just enough approximate the effect of one beer. Would that be close enough to the test that you proposed earlier?
